AT&T has sent a cool response to the Vuze Corporation's "Plug-In" survey of ISPs, ranked by their median rate of TCP reset activity: "Given that Vuze itself has recognized these problems with the measurements generated by its Plug-In, we believe that Vuze should not have published these misleading measurements, nor filed them with the [Federal Communications Commission]." So AT&T Vice President Charles Kalmanek Jr. wrote to Vuze CEO Gilles BianRosa, following the P2P content provider's FCC filing last week. And AT&T insists that it does not insert false reset signals into P2P packets.

"We're just putting this out there..."

Vuze sent the study both to AT&T and to the FCC. As Ars has reported [1], the company recently published a ranking of ISPs using a plug-in application that "measures the rate at which network communications are being interrupted by reset (RST) messages," in Vuze's own words. In November of last year Vuze petitioned the FCC to launch its present proceeding on ISP network management practices, especially after Comcast was accused of using reset packets to block ISP traffic.

According to Vuze's filing, 8,000 people around the world installed the plug-in, and the company collected over a million hours of data about reset activity on various ISPs. Comcast topped the chart, with one of its local networks having a median reset rate of 23.72 percent. Cablevision came in eighth with 17.58 percent, AOL arrived at 20th, and an AT&T Worldnet Services network landed at 25th with a median rate of 13.97 percent.
